How to work it out

  1. Divide the part by the whole: 24 ÷ 81 = 0.296296
  2. Multiply by 100: 0.296296 × 100 = 29.6296%
  3. Check: Work backwards: 29.6296% of 81 is 0.296296 × 81 = 24.

Another method. As a proportion of part to whole: 24/81 = p/100, so p = 24 × 100 ÷ 81 = 29.6296%. Both methods always give the same answer.

In a spreadsheet: =24/81*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.
